does anyone know if coffee grounds really help weed grow? how do you do it
Coffee grounds? I would think they would cause the plants to have anxiety. Maybe decaf would work though.
Fresh coffee grounds are highly acidic. I recommend composting them first; filter, too.
I've heard rumours about this. Im in suspense. Time to google
Consider it googled.....
Yes they are excellent choices as organic fertilizers. If you use them, use less or no synthetic (commercial) fertilizers. Since coffee grounds lack phosphorus (the key ingredience in fertilizers for flowering plants) it is better on non-flowering shrubs, foliage plants and grass than flowers. However, if used in combination with phosphorus (e.g. super phosphate or rock phosphate) it is excellent -- and cheap. You can buy super phosphate and rock phosphate at garden centers and home improvement centers.
Used coffee grounds contain about two percent nitrogen, about a third of a percent of phosphoric acid, and one percent potash; DRY WEIGHT. If you could buy coffee grounds in bags at garden centers the 3 numbers on the bag would be 2-0.33-1
It is not particularily "slow release" as typical of most organic fertilizers. Most of the nitrogen will be available pretty fast. This means you have to watch out not applying too high quantities at one time, and that more then one application during the growing season may be needed but in smaller volumes at a time.
Analysis of coffee grounds also shows that they contain many minerals, including trace minerals and carbohydrates. This makes it a good fertilizer.
Since coffee grounds are acidic they are particularly useful on those plants for which you would purchase and apply an “acid food,” such as blueberries, evergreens, azaleas, roses, camellias, etc. They would not be ideal around plants like lupins which require a sweet soil. If your soil is naturally alkaline (e.g. pH higher than 7.0) using coffee grounds is extra beneficial.
Since coffee grounds tend to get moldy, they should be incorperated into the soil, or dried and used as mulch.
If you have problems with too high pH, the use of coffee grounds are a good solution.
You can also dilute the grounds with water, and water the plants with the "tea" created. This is a good way to get plants growing immediately. Just avoid using around very small seedlings as it can burn the young plants. for established plants it is great.
use about 6 table spoons per plant dug in near the roots, or in pots. You can also mix in a 1/4 - 1/2" layer and mix it in thoroughly in the top of the soil. The coffee grounds will help aerate the soil and provide nitrogen and potash to the plants. The phosphorus, should be added seperately, however, such as rock phosphate (0-4-0) or super phosphate (0-20-0) available at garden centers.
Hope this helps...
Thanks for the post... I love drinking coffee and think every time if I should be saving those grounds.
i would like to know as well. once i was at starbucks and they are giving out free left overs! but i wasnt sure........
Great to compost if you need a more acidic soil you can add them right it. As they decompose they become a rich source of nutrients. I used to mix it in before I planted berry brambles because they like a acidic soil.
Just put a dab of coffee grounds behind your ear. It drives the women crazy...
I drink quite a bit of coffee, so yes it's nice to recycle.
I regularly add my coffee grounds to my compost piles. Other than a few twitchy squirrels it works great!!
Brambles.... that takes me back to my Uncle Jack's place when I was a boy. Uncle jack had tons of raspberry brambles. You'd have to be inflicted with a few barbs and scratches but the payoff was enormously worth it. Uncle Jack also had a pet wild mouse that would come out by his stove and eat from his hand. I was amazed as a youngster. It was years later with a "mother's" timing, I was informed that Jack had many many mice, not one. He just kept insisting it was just one My mom let me keep that positive spin on Jack till I was ready...... sometimes it's the little things. Thanks Mom...
+rep for bringing that one back from the cobwebs NG...
lol sweet coffe= goooddd
i have used coffee grounds (used) for my plants plenty of times it never hurt or burnt any of my plants before. I have also mixed liquid coffee with water as well. and never had any problems. could just gotten lucky. but it seemed to help a lot
1/4 or 1/2 of what type of measurement
1/4 or 1/2 of what type of measurement
how about instant coffee because that's all I drink lol! Some good information in this thread id never considered coffee grounds as a fertilizer before and probably still wont ever use them but its nice to know that its a viable option
Thank you for the education and laughs! Happy Growing!
Slightly different question on this topic... Has anyone ever flushed with coffee instead of/as well as molasses? I've just read that coffee is better during veg, but I'm a bit of a coffee fiend and I'd love to get some kind of Coffee Haze thing going on! Anybody have any thoughts/experience?
The Soil and Plant Laboratory Inc., in Bellevue, WA states that used coffee grounds contain 2.28 percent nitrogen, 0.06 percent phosphorus and 0.6 percent potassium - a healthy ratio for both the vegetative and flowering phases. I dig in uncomposted grounds into the soil and top/side dress a half inch or so as well as water with a tea made from coffee grounds/egg shells during the vegetative cycle with great results. During flower I stop the coffee tea watering. As I grow organically adding a sprinkle of hardwood ash around the base of each plant inhibits slugs, just a sprinkle because hardwood ashes, though high in potassium it is also quite acidic.
I feed mine iced coffee they like all the sugar
Question is it safe to use the coffee grounds in the K-Cups used in keurig Brewers like scoop it out and use it like a powdered nutrient and let it do its thing
So i could brew the not so strong Folgers coffe let it cool and just and just poor it in my plant cuz i just poured it down the sink cuz it got cold and its week
